Concrete Tube Calculator Calculate the volume of concrete needed to fill a hollow tubular form (annular ring cross-section). — free online calculator.

Formula

Volume = π × (R_outer² − R_inner²) × height
  • Concrete Tube Calculator calculates its result from Height, R Outer, R Inner. It uses the formula Volume = π × (R_outer² − R_inner²) × height. Change any input to recalculate the result instantly.
  • The main inputs are Height, R Outer, R Inner. Enter them in the units and format shown in the calculator.
  • Keep measurements and project assumptions consistent before comparing or combining values.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Concrete Tube

Inputs
  • Height: 2
  • R Outer: 3
  • R Inner: 4

Using Height = 2, R Outer = 3, R Inner = 4, the calculated result is -43.9822971503.
